Its that time again, when my tiers are worn out and they need to be replaced. This time around, I thought I’d try some cheaper tires because I simply drive my car to and from work and really don’t need anything special. I stumbled upon a number of cheap brands and most of those had really bad reputations. But then I found these MuchoMacho tires under the brand Cosmo.

I have always wanted a turbo engine. Now that my engine is at the end of its life I now have the opportunity to build one from the ground up. This gets into a whole mess of other issues that connect back to my earlier post about the limitations of the Gen 1 Chevy Small block, but forget about that for now, instead, lets explore the nature of turbos and why some turbos might not work for a given engine.

The SCCA and other sanctioning bodies typically have a rule that separates race tires from street tires for classing purposes. Currently, a treadwear rating of 200 is what this rule is based on. Any tire that is equal to or greater than 200 is considered a street tire, while everything below is a race tire. But there is a problem with this; the treadwear rating number, also known as UTQG (Uniform Tire Quality Grading) is arbitrary and means absolutely nothing.

Back in 2012, I wrote and article about how absurd Obama’s 54.5 mpg CAFE regulations were. You can see that article, which is still relevant, here. One of the things I mentioned in that article was how Jimmy Carter did a similar thing back in the 70’s but thankfully was repealed by the Regan administration. History seems to repeating itself because news came today that the Trump EPA is rolling back the totally insane Obama era plan.
